Hey guys, my Model A recently started - seemingly without rhyme or reason - getting into a "mood" where it will idle forever just fine, but if you even touch the throttle it immediately dies. Eventually it starts acting right again, like a switch was flipped, but nothing specific seems to cause it.

I recently had to replace the head gasket. I am currently running without a muffler (the exhaust manifold is about to be replaced with a custom unit and I didn't feel like putting the muffler back on just to immediately have to remove it a couple weeks later).

Here is some video.

Shortly after this video, I was able to tease the RPM up by gently pumping the throttle. It backfired through the carburetor and then began acting normally again:

Any input is appreciated.
